The present invention relates to a kind of acoustical tile composition that contains pearlstone, its used water felt technology is made roof tiles, have now found that it is favourable using the pearlstone handled, it reduced contain pearlstone, cellulosic fibre and preferred second caking agent, as the moisture trend of the composition of starch.Composition of the present invention also can contain conventional material, as mineral fibre and filler, as clay, gypsum and Wingdale.Preferably, perlite is handled also for good wettability is provided.
Have now found that containing the perlitic said composition of handling just can more effectively be used for production sound insulation roof tiles and panel with conventional water felt equipment.Have now found that and use the perlite of handling, rather than conventional untreated perlite, acoustical tile composition of the present invention can form the substrate that contains less water.Lower water content makes that substrate can be dry quickly, and makes equipment with higher linear velocity operation.The perlite that has now found that the processing with some water-wet behaviors can provide the production of sound insulation roof tiles and panel more efficiently, because be easier to form stable slip with the perlite of hydrophilic treatment compared with the perlite of handling with hydrophobic.Therefore, the perlite with processing of some water-wet behaviors is preferred.
Thereby reduce its aqueous trend although available diverse ways is handled pearlstone, handling pearlstone with silicone compounds usually is preferred to reduce its moisture trend.Not only comprise conventional siloxane polymer at this used term " silicone compounds ", and comprise that polymeric siloxanes, reactive silane monomer, silicon salt (salt of silane) and other can reduce organic material of the moisture trend of pearlstone effectively.
Acoustical tile composition of the present invention contains cellulosic fibre, and it can comprise newsprinting paper and/or useless acoustical tile and panel (fragment), and this is to environment-friendly place.The acoustical tile composition also can contain a spot of mineral wool or not contain mineral wool.Dried product can form than the acoustical tile that is purchased more sound damping watt and panel, and the acoustical tile that is made by the present composition has qualified physicals when being used in the roof system of suspension.
The present invention relates to a kind of acoustical tile composition that contains pearlstone, its used water felt technology is made roof tiles.Be applicable to water felt technology of the present invention comprise form with enough water comprise pearlstone, cellulosic fibre and preferred second caking agent, as the aqueous dispersions of starch so that dispersion liquid can flow.Aqueous dispersions flows on the mobile supporter streamline that has aperture, the wherein acting in conjunction by gravity and vacuum hydro-extraction, formed the material cake of dehydration, then to the material cake pressurization of dehydration (with or need not be other vacuumize) thus reach certain thickness to form substrate.Pressurization steps (with or need not be other vacuumize) further make substrate dehydration, subsequently substrate is sent in the drying oven, the humidity of substrate reduces to below 5% in stove, and the humidity of the finished product is preferably below 1%.
Acoustical tile composition of the present invention must comprise pearlstone and cellulosic fibre, and preferably also comprises second caking agent, as starch.The pearlstone that uses in the present composition must be handled so that reduce its aqueous trend.In optimized technical scheme, the present composition can comprise mineral fibre and clay filler in addition, and the concrete quantity of raw material of the present invention is not limited.The professional who is familiar with prior art will recognize to use and comprise that the perlitic composition of maximum quantity will obtain maximum benefit of the present invention, as long as keep the desired physicals of product.Usually, the present invention proposes the composition that contains the following composition of in table 1, expressing quantity.
Table 1
| Composition | Weight percent (used scope) | Weight percent (preferable range) | Preferred percent |
| Perlite | Be not more than 75% | 15-70％ | 50％ |
| Cellulosic fibre | Be not more than 25% | 3-20％ | 18％ |
| Starch | 0-15％ | 3-12％ | 7％ |
| Latex | 0-10％ | 0-5％ | 0％ |
| Filler | 0-25％ | 0-20％ | 20％ |
| Mineral fibre | 0-85％ | 5-65％ | 5％ |
| Total amount | 100％ |
Acoustical tile composition of the present invention replaces conventional pearlstone based on the pearlstone that treated moisture trend reduces.Composition also must contain cellulosic fibre, and preferably contains at least a other caking agents that comprise starch or latex.Composition preferably contains mineral wool and filler, as clay.Composition also can contain other admixtures, and as thickening material, flocculation agent and tensio-active agent, they are usually included in the batching of sound insulation roof tiles.As mentioned above, composition can contain some mineral wools (on a small quantity), yet, have now found that composition of the present invention can be used for making the acoustical tile or the panel of no mineral wool.
The pearlstone of acoustical tile composition of the present invention to use treated moisture trend to reduce.Have now found that compared with untreated perlite, can come the exsiccant advantage with less energy to such an extent as to use the perlite of handling to provide the substrate water content obviously to reduce substrate.Guaranteed that by the substrate that uses the perlite of handling to form moisture content less product is dry quickly, and made whole water felt streamline with higher speed running.
Have now found that the inevitable existence in two ways of water in the sound insulation roof tiles dispersion liquid, i.e. " freedom " water and " combination " water (water or the capillary water that also claim absorption).Free water is defined as the water that machinery shifts out in the energy slave unit, comprises the water with pressure portion that maybe need not vacuumize and pass through equipment and pipeline discharging.Combination water is defined as the water that combines and can not machinery shift out (as suction or pressurization) by hydrogen bond or capillary action with cellulosic fibre or other solids components.The combination water that exists in the substrate requires heating just can remove, and therefore must just can remove in moisture eliminator.The retention value of water (WRV) is defined as the percentage ratio that combination water accounts for the dry weight of sample
The water that exists in the substrate after moulding (promptly vacuumizing and the back of pressurizeing) mainly is combination water.In these combination water, determined that now the water of staying in the perlite particle micropore approximately constitutes 66% of the whole combination water of roof tiles substrate for the roof tiles substrate that comprises 45% mineral wool, 32% perlite, 5% starch and 18% paper fiber.For the roof tiles substrate that comprises 5% mineral wool, 50% perlite, 7% starch, 18% paper fiber and 20% gypsum, this value approximately is increased to 83%.The representative of paper fiber is to second largest material of combination water contribution, and in above two kinds of batchings, their water content is respectively 17% and 13%.
Except the preferred starch caking agent of pearlstone, cellulose fiber peacekeeping of indispensable processing, the present composition also can contain other caking agents.As latex and filler, as clay, gypsum and Wingdale and other conventional admixtures, admixture comprises thickening material and tensio-active agent, and they are included in the batching of sound insulation roof tiles usually.As mentioned above, composition can contain some mineral wools (on a small quantity), yet, have now found that composition of the present invention can be used for making the acoustical tile and the panel of no mineral wool.
The composition of most critical is a perlite in novel sound insulating of the present invention watt composition.Pearlstone is used for the acoustical tile composition and is widely known by the people in the prior art.Pearlstone and other aglite materials also are used in the acoustical tile, because their costs and density (being 3-5 pound/cubic feet) are lower.Thereby pearlstone provides packing volume and pore to improve sound-proofing properties to composition.Have now found that the lower pearlstone of density (being 3-5 pound/cubic feet) provides competent packing volume and pore.Pearlstone is treated has in the present invention reduced perlitic water content.
Perlite generally includes after any heating volume expansible glass rock greatly, and it is similar to obsidian, and comprises the volcanic ash glass that ryolite is formed especially.Perlite contains 65-75%SiO usually
2, 10-20%Al
2O
3, 2-5%H
2O, and a spot of yellow soda ash, salt of wormwood and lime carbonate.Pearlstone refers to any glass rock, and expands suddenly when more particularly referring to rapid heating or the volcanic ash glass of " quick-fried expanding "." quick-fried expanding " when being heated to the temperature of initial fusing, the perlite particle of fragmentation usually takes place.Contained water changes water vapour and broken perlite particle into and forms lightweight, velvet-like, soft particle through expanding in the particle.The volume of particle usually increases by ten times at least.Pearlstone is characterised in that usually it is concentric, spherical fissured system, and this is called perlitic structure.Dissimilar perlites be characterised in that the size that influences each performance such as softening temperature, expansible type and degree, bubble and the wall thickness between the bubble, and the glass of the void content of product form different.
In the ordinary method of preparation pearlstone, at first the perlite ore deposit is milled to very thin size.By in the warm air that levigated perlite ore deposit is incorporated into the pearl stone puffing device and with pearl stone puffing.Typically, puffing apparatus arrives about 1750 temperature with air heating.Heat perlitic warm air and carrying the levigated perlite, and it is expanded as snuff is quick-fried, thereby form the pearlstone that density is approximately 3-5 pound/cubic feet.Pearlstone is very light material, but it contains a lot of minute cracks or minute crack.When pearlstone contacted with water, water infiltrated in crackle and the crack, and entered in the air of filling the perlite hole.Cause thus in expansible perlite particle, containing a large amount of water.
The present invention proposes to handle pearlstone to reduce the method for perlite water content, forms hydrous slurry when perlite mixes with water simultaneously.Have now found that handling perlite with silicone compounds has reduced water and infiltrate trend in crackle and the crack, and therefore reduced perlitic water content.Usually the minimizing of water retention value is relevant with the quantity of use silicone compounds in perlite.
At this, term " siloxanes " not only comprises conventional siloxane polymer, comprises that also polymeric siloxanes, reactive silane monomer, silicon salt (salt of silane) and other can reduce organic material of the moisture trend of pearlstone effectively.Can be used for handling pearlstone is various siloxanes such as polydimethylsiloxane (PDMS), silane such as iso-octyl trimethoxy silane and their mixture with the silicone compounds that reduces the pearlstone water content.Organic alcoxyl silane is preferred reactive silane, because they can be converted into siloxanes on the perlite surface, and can not produce corrosive by product, and the therefore on-the-spot silicone film that forms.
In optimized technical scheme, thereby handle pearlstone to form moisture trend and reduce and to be easy to mix the perlite that is formed on the flowable slip that uses in the water felt technology with water with the silicone compounds that not only has hydrophobic character but also have a water-wet behavior.
Preferred silicone compositions has utilized the polydimethylsiloxanebackbone backbone with hydrophilic side chain.These materials comprise the OSi ALE-56 of the DC108 of amino polydimethylsiloxane that replaces such as Dow Corning and OSiInc and have the polydimethylsiloxane of polyether lateral chain such as TEGOPREN 5830 and the TEGOPREN 5863 of GoldschmidtChemical.
Preferred silane material is made up of hydrophobic and hydrophilic silane mixture.Hydrophobic silane provides desired water tolerance, and hydrophilic silane provides desired wetting ability.Hydrophobic silane material comprises the BS1316 of iso-octyl trimethoxy silane such as Wacker Silicones and the OSi A-162 of methyl trimethoxy oxosilane such as OSi.Hydrophilic silane material comprises three alcoxyl silane such as Dow Corning Z-6011 and the Dow Corning Z-6022 that contains amido functional group.Other hydrophilic silane materials comprise 3-Racemic glycidol oxygen propyl group trimethoxy silane such as Dow Corning Z-6040 and chloropropyl three ethoxy silane such as Dow Corning Z-6076.The mixture of hydrophobic silane and hydrophilic silane combines and is used to provide desired various performance.Other available silicone-type materials are described in the following embodiments.
Thereby the present invention proposes to handle the retention value that pearlstone reduces the water that does not rely on perlite density and size with silicone compounds.
The present invention also proposes to use some by the aglite that born of the same parents' shape microballoon of sealing is formed, and it can be used for replacing the perlite of some or all above-mentioned processing.Suitable sealing born of the same parents shape micro-sphere material comprises the glass microsphere sold by 3M, the Q-Cell product of being sold by Philadelphia Quartz, the Dicaperl that comes from Grefco Corp
TMPerlite material and come from the Sil-Cell of Silbrico
TMThe perlite material.Because these materials mainly are born of the same parents' structures of sealing, even not handle with silicone compounds, they just have the retention value of lower water.Yet, handle the retention value that these micro-sphere materials can obviously reduce their water with suitable silicone compounds.
It is a kind of that to be used for handling the specially suitable perlitic method of existing discovery be to form the water miscible liquid of siloxanes and it is sprayed onto the hot perlite that comes out from stove.Water in water miscible liquid evaporation subsequently, and siloxanes solidifies on perlite.Among the embodiment 1 below another kind of method has been described.Being used to handle perlitic another kind of method is directly to spray silicone compounds (siloxanes or silane) on perlite.
Used perlite ore deposit is to buy from the Harborlite Corporation of Antonito, Colorado among the described below embodiment, and expanded with the industrial bulking equipment of USG Corporation.The perlite ore deposit (being included in the USG settling at Lovelock and Nevada place) of assessment different sources.Because the characteristic in perlite ore deposit notices there is not what difference during pearl stone puffing or substrate formation.The size of pearlstone particle is not crucial.And thin especially perlite size seems there is no need.Can use the following pearlstone of size test.

In novel sound insulating of the present invention watt composition, second kind of main component is cellulosic fibre.It can be used as the volume weighting agent, and initial strength is provided.Cellulosic fibre also can be used as jointing compound and keeps micro situation.Assess the situation of several cellulosic fibres in these compositions.It is well-known using newsprinting paper in the acoustical tile batching, and assessment sledge mill and the situation of water slurry newsprinting paper in these compositions.For the consideration of price, newsprinting paper is preferred.Purified paper fiber and xylon also can be used as the source of cellulosic fibre, yet, have now found that the roof tiles that makes with xylon (no matter being cork or hardwood) is difficult to cut with cutter when mounted.And xylon is a kind of more expensive cellulosic fibre source.
The third major ingredients of the present invention is the caking agent composition, although cellulosic fibre can provide as the enough bonding forces in unique caking agent source, comprises also that in composition second kind of caking agent such as starch then are preferred.Can be when needing or do not use other second caking agent such as latex with starch with starch.Starch is from the most effective and preferred caking agent of cost.Using starch in the mineral wool acoustical tile is well-known as caking agent.Thereby can be that viscous gel prepares starch gel until the abundant slaking of starch and with the slip multiviscosisty by being dispersed in starch particle in the water and heating slip.Before slaking, the part of cellulosic fibre can be incorporated in the starch slip.The curing temperature of control starch slip is fully expanded to guarantee starch particle closely.The typical curing temperature of cereal starch is approximately-195 of 180F (82 ℃) (90 ℃).Starch also can be through precuring and as caking agent, because it can form gel in the drying substrates process.
The latex caking agent can be used for replacing starch or uses with starch and cellulosic fibre caking agent.Many latex caking agents that use in sound insulation roof tiles batching are disclosed in US5250153.As mentioned above, one of problem of the sound insulation panel of use starch caking agent is that starch caking agent pressure falls into, particularly under higher humidity condition.It is well-known using thermoplastic adhesive's (latex) in the prior art in the mineral wool acoustical tile.These latex caking agents can have about 30 ℃-110 ℃ glass transformation temperature.The example of latex caking agent comprises the phenylethylene/butadiene of polyvinyl acetate, vinyl-acetic ester/ACRYLIC EMULSION, Ethylene Dichloride, polyvinyl chloride, styrene/acrylic acid co-polymer and carboxylation.Prepare roof tiles of the present invention and can not use starch or latex.But preferably use at least a in the two.In optimized technical scheme, composition comprises cellulose fiber peacekeeping starch.
A kind of optional ingredients (in the sound insulation composition neither new constituent) is a clay, when hope has resistivity against fire (by ASTM Test No E119 definition), the clay of use at least 4%, preferably at least 10% (weight) likes necessity well in the roof tiles batching, because at fire testing medium clay soil generation sintering.In following examples, use the ball clay that is purchased from Gleason, Tennessee.Used other clays comprise the CTS-1 from the KT clay of Sledge, MS, from the CTS-2 of the KT clay of Sledge, MS, and from the Spinks clay of Gleason, TN with from Hickory, the Old Hickory clay of KY..In the roof tiles batching, can use other industrial clay such as kaolin and wilkinites etc.
In addition, acoustical tile composition of the present invention also can contain that class mineral wool, mineral filler such as mica, wollastonite, silicon-dioxide, gypsum, plaster and the lime carbonate that uses usually, other light filler, tensio-active agent and flocculation agent in acoustical tile.For the professional of the prior art of being familiar with preparation acoustical tile composition, these compositions are well-known.
